Heres an example since A is a square matrix while B and C is not. The program on my head is a row and a colum counter then if the row and colum is equal to eachother then the system will print out that the A matrix is a square matrix and both B and C are not. Is their efficent way on doing this?
{7, 2, 1},
A = {0, 4, 2},
{5, 7,11} {1 },
C = {2, 3, 4},
{5, 6 }
{1, 4},
B = {2, 8},
{1, 6,}
